How will a wireless device use dynamic rate shifting to maintain data integrity as a mobile user moves farther and farther away from the wireless transmitter?

How will a wireless device use dynamic rate shifting to maintain data integrity as a mobile user moves farther and farther away from the wireless transmitter?

• The wireless device will use a lower data rate.
• The wireless device will use an increased data rate.
• The wireless device will use maximal-ratio combining.
• The wireless device will use transmit beamforming.

Explanation: Dynamic rate shifting will maintain the integrity of data by triggering a shift to a less complex modulation and coding scheme, which will also result in a lower data rate between the wireless device and distancing mobile user.
